This lesson will explain in detail the complete processes of meiosis. What it is used for, and why we need it. Explain crossing over, haploid, and diploid. The students will look at diagrams of crossing over as well as the diffrences of mitosis and meiosis to show and explain the diffrences. They will have to draw out the steps of meiosis.
Learning Performances
The students will be able to explain the differences between mitosis and meiosis, and explain the complete process of meiosis.
I will start off by collecting and checking all of their homework. Then I will start by talk about what we did the day befor by asking questions like, Name one this that is different between mitosis and meiosis? What is diploid? How do you get different traits? From there I will handout a sheet with all of meiosis on it.
Instructional Activities
With the sheet on meiosis I will go through the steps one by one, either telling them that either that’s just like mitosis or the difference. If there is a difference then I will go into detail explaining it. Ex. Crossing over during prophase 1, meiosis 2 completely step by step. I will say, Look at the picture of prophase 1 is it the same ore different them mitosis? While doing this the students will have a blank worksheet that only has cell membrane and they will have to draw a picture of what is going on at that step as we go over it. With doing it like this even though it is like a lecture it's not me standing up in front of the class and they will be filling in work as we go along. I am hoping to get the whole class involved by not looking for individuals to answer but for the whole class to say either yes or no, and if it is no then calling on a students to tell me what is the difference. I will hand out a handout of crossing over and go over it in detail. This is a new concept for them. So I hope that after I am done explaining this to them that they will have questions.
Concluding the Lesson
To conclude this lesson I will give them a handout that has the differences between mitosis and meiosis on it for them. This is a great reference sheet for the students. Will ask them if there is anything that they are confused about.
Assessing Student Understanding
The assessment for this will come later on. A day like today is tough because it is a lecture. They will be getting a lot of information that they will need to know and understand before we can move on.
Cautions
With i lecture like this i believe that I will have to keep asking the class questions so that hopefully I won't loose them.

The students will have handouts on everything that I will be talking about. They will be able to follow along and write anything that they need write on the papers. With this they can visualize what I am talking about and they can keep it to reference back to.
